The United States was the leading destination for top scientists from all over the world. That is ending. Politicians ended it. It will cripple our future competitiveness. And it’s such a bitter tragedy. Almost no Americans, Conservative or Liberal, grasp what is now being stolen from them.

The US is the purple line bottoming out. Our economy may still roar, but we’re killing ourselves. Hoarding wealth, refusing to even ensure our kids have enough to eat. That line is an indictment. It reflects our warped values.

Trains are good. More trains please.

What a pleasure.

Dear U.S. media and commentators: Referring to the lovely Reagan/tariff ad produced by Doug Ford's Conservative government of Ontario as an ad posted by "The Canadian government" is like referring to Gavin Newsom's administration as "The U.S. government." Please up your info-processing game.

If the NIH and HHS were under any other prior President (Dem or GOP), we’d see a rapid shift of funding to leverage this. But the politicization (and gutting) of these agencies means it won’t happen—and so many people will die unnecessarily as a result.

It's hard to overstate how fully engaged Chicago and the surrounding suburbs are in this ICE madness. There are neighborhood watch alerts, spontaneous crowds gathering outside schools at pick up & drop off plus madly blowing whistles and honking car horns, this city is fighting back and hard.

The US Administration has explicitly chosen to make it much harder to build a career in research in the United States. This policy of hollowing out our future innovation capacity will ultimately harm every Conservative and Liberal American.

Another disturbing example of how Trump silences dissent: "the chief content officer for our parent company... stated in a meeting that we should not run articles that could draw the attention of the Trump White House and have them try to shut us down." www.politico.com/news/magazin...

Trump canceled trade negotiations with Canada over what he called a “fake” ad that featured parts of an anti-tariff speech by Reagan given on April 25, 1987. The ad uses unedited clips from the speech. See for yourself. Speech: www.presidency.ucsb.edu/documents/ra... Ad: youtu.be/hN_CVvzExpM

I seem to have written a book, for the first time. I suspect that my publisher will want me to talk about this more, so stay tuned, if interested.

This is among the most corrupt things a president has ever suggested, and I hope the press treats it that way. www.nytimes.com/2025/10/21/u...

1/2 First Ladies and the WH East Wing Office..

If some West Wing-type drama ran an episode where a deeply unpopular president faced the largest mass protests in several generation, and then ended it with visuals like this critics would universally pan it for the grossly over-the-top symbolism.

Someone just liked my tweet from 2024, and hence, I saw it now, too. Just imagine..

The whole thing as a vanity exercise to demonstrate a show of force before the No Kings events. DOD had said that firing bombs over a highway was safe; state officials disagreed and shut down the highway, used by about 80K people daily. Turns out the state officials were right.

Thanks again, Gavin--good decision. These frigging idiots!

This is what democracy looks like. #NoKings

I thought at least 10k people at #NoKings Santa Barbara today—Indivisible figures 13k. Not bad for a town of 85k.

somewhere in portland, there's one person, or a small handful of people, who came up with the inflatable costume idea, and I feel like they deserve our immense respect for defining the obvious developing aesthetic of the contemporary battle against fascism

So proud of my city. No Kings, Chicago!

Santa Barbara No Kings 2. Waiting for crowd estimate but compared to NK 1: Bigger, broader age distribution, signs less playful, more emphatic, angrier. No counter protests, happy crowd in sidewalk, helpful cops blocking traffic. Coastal California!

NYPD announces that zero arrests were made at the massive No Kings protests today after Republicans spent days claiming the protestors are violent terrorists.

Across all the major outlets — NYT, WSJ, WaPo, LAT, CNN, ABC, CBS, Fox News, NBC, CNBC, NPR, Bloomberg — the only outlet without a No Kings story on its home page is CBS News. For every other outlet, it's near the top. Even Fox News is running with "Nationwide unrest looms as thousands mobilize"

😍 Boston, you are beautiful. #NoKings

Now 5 have joined. 4 remain.

NHANES runs mobile clinics that travel the country measuring height, weight, & blood pressure while collecting blood and urine samples. These samples are our only national source for tracking everything from blood sugar to hormones, heavy metals, and more. The entire operation has been eliminated.

"We must not allow these attempts to control what can be taught, studied, or spoken on our campuses." Joint statement on "compact" by student leaders at targeted institutions. Well done.

Photos coming out of Western AK are devastating. Hardest hit are indigenous villages off road system, many miles by air from supplies. Most built on river deltas w/ no high ground to which to escape. Cuts to NASA/NOAA mean worse weather data. Cuts to EPA mean no grants for erosion control. Etc.

Happy Thanksgiving, folks. Miss you.

Good for them: it is a violation of the Hatch Act that limits the use of public assets for partisan messaging. Orgeon has its own version of that law, and covers those who run the airport. Other airport administrators should look to see if they are in the same position.

After Trump got his Covid shot, he chose to fire the scientists protecting the rest of us from diseases.

If you don't follow the courts, you may not realize how absolutely unheard of it is for sitting federal judges to say ANYTHING on the record about other federal judges — let alone this: “a war zone” “judicial crisis” “incredibly demoralizing and troubling” “have not been models of clarity”

Well, Trump didn't get the Nobel he wanted, but University of California researchers have done well this week.

The Virginia Senate just told UVA it’s not getting state funding if it accepts the compact since UVA exists to serve Virginia, its residents, & their interests—not be a tool of the federal govt. Scoop from our student newspaper, who’ve been doing vital reporting www.cavalierdaily.com/article/2025...

We are building a new pop center at UofT and will hold our first mini-conference on Nov 6 - come join us!! Exhibit 1: amazing speaker line-up - featuring friends around the world to discuss why demography/pop center matters! 🤓 Exhibit 2: the iconic castle where this conference will take place 🏰 ✨

If highly selective universities, meaning those that admit <=10% of applicants, selected only on HS GPA, 63% of incoming students would be women. Wouldn't change much if considered test scores. Trump's "compact" would hurt young men, and esp. young white men. I doubt Linda "A1" McMahon knows this.

Motivated reasoning is very powerful in economics. But focused and creative empirical research wins.

Pentagon warns Toronto ‘dangerously close’ to winning World Series

This is nothing more than a continuation of the president’s desperate weaponization of our justice system. I am not fearful — I am fearless. We will fight these baseless charges aggressively, and my office will continue to fiercely protect New Yorkers and their rights..

Wow. My University of Washington colleague Amy Hagopian was expelled from APHA for her pro-Palestinan advocacy. 🧵 academeblog.org/2025/10/07/w...

This is a must-read for anyone reporting on the Trump regime's proposed deal with 9 universities. Conclusion: "Universities’ only proper response to this “compact”...is to offer absolutely nothing." Don't miss the speculation about why these 9--prestigious enough but potentially soft targets.

Chemerinsky: The Trump extortion demands are unconstitutional as well as odious (gift link). Me: Any school that signs must be shunned, faculty affected must walk. No room for this.
